conclusions (1) AeroCom-II ACCMIP vs. ACCMIP annual means are identical – except for ship-emissions (2-6% smaller for only 1980 and 1990 in AeroCom (-II ACCMIP ) due to the linear time interpolation procedure taking into account the *true* original timestamps) – except for biomass burning emissions AeroCom biomass burning has strong inter- annual variations (1980 to 2006) - ACCMIP not AeroCom is CF compliant - ACCMIP not

conclusions (2) AeroCom-II ACCMIP vs AeroCom-II HCA0 v1 old SO 2 data – AeroCom ACCMIP has lower anthro. SO2 emissions Europe after 1990 (~ half less) & Asia (~ 30% less) – AeroCom ACCMIP has higher anthro. OC emissions Europe after 1990 (~ double) & Asia (~ 50% more) – anthrop. BC emissions are comparable
